Thank you for your idea. Firstly I printed it to use with my 540 motor. Later, after tests, it helped me, to understand, that I want to create my own 2-speed gearbox from scratches (unassembled on photo). Right now I working on metal important upgrades for it.
I managed to stuck the 32:1 version coupled with 1800KV Fusion inside my Bamboo WT - To get the gearbox out, the front mask must be removed and i also had to cut some generous windows into the "tunnel" and other parts.
The gearbox is gorgeous and i really love the way it's bolted together - as easy as the original!
Thanks Knur! This spool holder was designed like you knew the exact dimensions of the 3D printer location in my lab! I re-mixed the design for only 1kg and smaller spools, but I will print the larger version if I run 2kg spools in the future. This is the first print I have done with a 0.8mm diameter nozzle and it snaps on the frame of the printer really well!
